High temperature self-locking threades fastener

ABSTRACT

Thin invention describes self-locking threaded fasteners having a patch or patches of fused high-temperature-resistant resin adhered to a portion of the threads, providing self-locking capabilities at temperatures above 400 DEG  F,*&lt;FOO ID=308.1&gt;* 204 DEG C&lt;/FOO&gt; well beyond the range of temperatures attainable using prior art patch materials such as nylon. A process for making such fasteners by spraying finely-divided high-temperature-resistant resin powder onto the threads of a fastener also is claimed. &lt;IMAGE&gt;
